I figured this would be a nice thing to have on hand for those that have wanted, or want to record videos of themselves gaming or videoing your clan scrimmages or whatnot.
First, when in game open your console and type 'record name' (without the quotations), and where name is the name of whatever you want the video to be titled so for instance record scrim
After you're done playing, or wish to stop recording the game open console again and type stop
Once the video is finished you can watch the video by opening console and typing in 'playdemo name', but again, without the quotations.
Lastly, once you have recorded a video it will end up in your C:/Program Files/Steam/steamapps/username/insurgency/insurgency
Hope this is helpful, and clear
! Happy gaming guys and gals.
